“…In 1948, Taylor and co-workers reported for the first time in a short communication that silica–alumina catalysts were capable of inducing H/D exchange between CH 4 and CD 4 at temperatures above 340 °C . About two decades later, Larson and Hall reported that on an alumina catalyst, H/D exchange occurred between methane and surface hydroxyls of alumina at room temperature. An Arrhenius analysis of the alumina system demonstrated that the reaction had a low apparent activation energy of 5.7 kcal mol –1 (Table ). Their studies showed that there was a direct reaction between the alumina and methane, and that there was a normal primary KIE of ∼2, when comparing the rates of disappearance of CD 4 (on protio alumina) and CH 4 (on deuterated alumina) in separate experiments, indicating that the C–H/D bond breaking step occurs prior to or during the rate-determining step.…”

“…Due to the topological type of CHA structure, SAPO‐34 had good shape selection and was widely used in the MTO reactions 17 . It is notable that the acidity of SAPO‐34 assumes a significant part in controlling product selectivity 18 . The acidity of SAPO‐34 comes from the fact that Si enter the AlPO 4 zeolite framework through isomorphic substitution.…”
